I’ve never been to a Worldcon, but I’m thinking I ought to for when it’s in my backyard.
George R. R. Martin, however, has been to just about every Worldcon he could for several decades running.
This year’s WorldCon is in Dublin, so the Irish Times caught up with him and he mused on WorldCons and fandom and all sorts of things.
If you want more of Martin musing on his career and art, you can also catch an interview of him on Maltin on Movies.
